Bang, bang bang! Lots o' questions! Never had an opportunity like this before. I love Hondas!
Those mini four strokes are adorable! Keep pumping them out!
A few questions on the GCV 160.. Does it have a timing belt tensioner? I just looked on the honda engines website and it doesn't show one. Hoping it won't stretch! I tried to help out a neighbor with a Ryobi 4 stroke, only a year old and the timing belt was badly stretched. I tried to rig up a tensioner but it didn't work.
As we further progress into reduced emissions and fuel economy mode, everything helps, what rpm are the valve springs good for? Could they be lightened? I am thinking that since it is usually running 3000-3600rpm, the valve springs should be very light, like float begins at 4000 rpm. I just did a valve adjustment on the GCV 160 recently (PITA to get that valve cover off btw), I don't remember how stiff they were, but remember thinking they could be lighter.
Any EGR or catalytic converters in the works for the little ones?
My auto-choke is working like a dream, I can start mowing right after starting without a hiccup. But I usually start it up and manually move the throttle to idle to let it warm up for 15 seconds or so before mowing. Otherwise....Fuel injection please!
As far as marine engines, is the BP60 based on the 1.0 3 cylinder from the 1st generation honda insight?
The BP135 and 150 have variable intake manifolds and are essentially marine K24s. Any plans on taking those sweet variable intake manifolds and bringing them to the automotive world?
I'm new to marine engines, but what is with the different power ratings on otherwise seemingly the same engine? Different fuel maps? I'm thinking the headers and intake should be reduced diameter if they are optimized for each power rating.
I think that's all for now, since your expertise is in the marine and small engines areas.
I currently have two rare honda's in the stable, and looking to add more. A 2006 Accord V6 6 speed manual sedan (less than 30,000 made in total), and a 1988 CBR 250R (MC19), a four cylinder 250cc only sold in Japan!
